8 Claims.

This invention relates to coil holders such as are used to rotativelyretain a coil of strip material and adapt it for progressive delivery toa machine subjecting it to a shaping, cutting, perforating or otheroperation.

An object of the invention is to adapt a holder to concurrently receiveat least two coils of strip material so that time may be saved infeeding such material by loading a full coil into the holder prior toexhaustion of the coil then occupying the holder.

Another object is to provide for the reception of two coils of stripmaterial by a carriage movable On a suitable base in a directiontransverse to' the coils so that either coil may be readily establishedin a required feed position.

Other objects are to adapt a coil holder to be readily adjusted toaccommodate coils of various widths; to definitely provide againstbodily withdrawal of a coil from its feeding holder under feedingstress; and to provide adjustable means for limiting travel of acarriage for receiving two coils.

These and various other objects the invention attains by theconstruction hereinafter described and illustrated in the accompanyingdrawings, wherein:

Fig. 1 is a view in side elevation of the improved holder showing a coilfeeding therefrom.

Fig. 2 is a front view of said holder.

Fi 3 is a vertical sectional view of the holder taken upon the line 33of Fig. 2.

Fig. 4 is a sectional detail of an antifriction provision for journalinga roller, taken upon the line 3-4 of Fig. 1.

In these views the reference character I designates a. base plate formedof heavy sheet metal having a pair of T-shaped rails 2 welded orotherwise rigidly attached thereto along its front and rear margins.Upon each rail 2 there is adapted to travel a number of spaced rollers3, journaled on the front and rear ends of shafts 4. Suspended by andbeneath the shafts 4 is the bottom plate 5 of a coil carriagetravelingon the rails 2, such plate seating on horizontal flanges G of apair of heavy angle bars I having vertical flanges perforated to receiveand journal the front and rear portions of said shafts. The rollers 3are annularly flanged in proximity to the angle bars I, being thus.restrained from material movement transverse to the rails. Travel of thecarriage is limited by stops la: slidingly fitted to the head and web ofthe front rail and held selectively positioned by set screws lb.

Welded to or otherwise rigidly mounted on the plate 5 at its lateralmargins is a pair of upstanding vertical sheet metalplates 8, and a pairof slightly spaced sheet metal plates 9 parallel to the plates 8 iswelded or otherwise rigidly secured to the mid portion of the plate 5and projects upwardly therefrom. Mounted jointly in each plate 8 and inthe relatively adjacent plate 9 is a set of rollers l0, ll, l2 and i3extending the full distance between said plates and each carried by ashaft l4 having end portions projecting through said plates and clampedthereto by nuts IS. A set of suitable antifriction elements It isinterposed between each end portion of each roller and the correspondingshaft l4. Each plate 8 and the relatively adjacent plate 9 are furtherinterconnected by a spacer bar l'l' having reduced ends extendingthrough said plates and engaged by clamping nuts l'la.

Each plate 9 forms the inner wall of a coiled stock receiver, and outerwalls for such receivers are formed by plates I8 adjustable to and fromthe plates 9 to accommodate the receivers to coils of different widths.The plates it are spaced above the bottom plate 5 of the carriage, theirlower edges being positioned substantially at the rollers "I, ll, l2,and I3, and said edges having tongues l8a projecting between therollers. The plates iii are provided with front and rear supports, thelatter consisting of collars l9 engaging the spacer bars l1, each ofsaid collars comprising a lower portion welded to the correspondingplate l8 and an upper portion bolted to the lower portion and thusclamping said collars to the corresponding bar H. The front support forthe plates l8 consists of angle brackets 20 suitably rigidly secured tothe lower portions of said plates exteriorly of the coil receivers andclamped by bolts 2| to raised portions 22 of the plate 5, said portionsextending forwardly at a gradual downward inclination. The portions 22are slotted as indicated at 22a transversely of the coil receiver toaccommodate the bolts 2| in various adjusted positions of the plates l8,and the collars l9 and brackets 20 serve jointly to hold the plates l8in any adjustment.

The receiver-forming plates 9 and i8 have tapering upward extensions 23the end portions of which are flared to diverge at a gradual angle, saidportions 23 serving to guide coils of stock into the receivers, whetherrolled into place from the front of the holder or lowered by an overheadhoist or crane. To facilitate rolling coils into the two receivers, aninclined platform 24 is detachably engageable with the front angle bar8, I, the raised rear portion of such platform having a depending flange2% adapted to be hooked over said angle bar while the forward edge ofsuch platform rests on a'fioor.

The mid portions of the plates 8, 9, and I8 are correspondingly formedwith similarly located slots 25, inclined at an angle of 30 or less tothe vertical, having their upper ends of an enlarged circular form asindicated at 25a. Mounted in said slots of each set of plates 8, 9, andI8 is a bar 28 rigidly carrying on its end portions a pair of collars 27proportioned to be passed through the enlargements 25a, in engaging saidbars with the plates and preventing escape of the bars from the plateswhen the bars are lowered into the narrower portions of the slots. Thesebars are inserted, as described, after positioning coiled stock in thereceivers, and in extending through central openings formed by thecoils, said bars prevent bodily removal of the coils from the receiversdue to feeding stresses, if for any reason the stock ceases to uncoil.

In use of the described coil holder, after adjustment of the plates H!to receive an intended width of coiled stock, the latter is rolled orlowered to a position on the rollers H), II, I2 and I3 in one of thereceivers, and the exposed end of the stock is connected into a machine(not shown) to which the stock is to be fed. At any time duringuncoiling of the stock, a second coil may be introduced into the otherreceiver, and as soon as the first coil is exhausted the carriage may berolled laterally along the rails 2 to locate the second coil in properstock delivery position. The first mentioned receiver, now empty, may beloaded with still another coil while stock is being fed from the secondone. Thus delivery of stock to a machine may be maintained with aminimum interruption, by loading each coil receiver during feeding ofstock from the other, the delay in starting a full coil being only thatinvolved in rolling the receiver carriage a short distance on its baseand connecting the full coil in feeding relation to said machine. Theincline 22 serves to temporarily support coiled stock during removal ofits fastenings and preliminary to delivering it to the rollers l0, ll,i2 and IS. The roller ll is at a level slightly lower than those of therollers l and I2, so that the roller tends to counteract any tendency ofa coil to escape forwardly from the rollers. The rearmost roller I3 isat a materially higher level than the other rollers so as to stronglyresist any tendency of a coil to leave the rollers in a stock-feedingdirection.

The stops 1a determine limiting positions of the carriage such as toestablish the two coil receivers in the same relation to the base land'hence in the same relation to any machine to which strip stock is beingfed. Adjustment of these stops permits carriage travel to be suited tovarious widths of strip stock.

The invention is presented as including all such changes andmodifications as come within the scope of the following claims.

What I claim is:

1. A holder for coiled stock comprising a. carriage providing twosubstantially similar laterally adjoined receivers for coiled stock andhaving an anti-friction provision for the rotation of coils in suchreceivers, a base, a rail on the base, guiding the carriage in a travellateral to said receivers, and adapting the receivers to bealternatively established substantially in a certain position relativeto the base, and stops ad- Justable on said rail to determine selectivelimiting positions of the carriage.
